First Looks: Thermapen Thermometer

I finally got a Thermapen thermometer.  Manufactured by ThermoWorks, this thermometer is lauded by many.  I was excited when it showed up the other day!

The shipping box says… ThermoWorks.  
That’s good because you know it’s from ThermoWorks that way. 🙂

I was able to do just a little bit of testing with this.  I was mainly interested in response time.  With some limited testing, with warm water, I was impressed by how quickly this honed in on a temperature.  Three seconds seems realistic.

    I just purchased one from the open box sale, so I was limited to white, pink, or tan. Paid $74 for the thermapen and $18 for a leather wallet carrying case. I was very impressed with the response time for reading the temperature. Kind of pricey, but I don’t mind paying for quality. I’m sure it will last for years.

    I’ve been using the thermapen for about a year now for brewing and pretty much everything else. It’s a great investment (I paid the new price). It gives you an instant read which is great if you’re mashing and don’t want to leave the lid off the tun very long. One thing I will say is I wish it had a longer probe to check deeper into the mash. Other than that it’s one of the best brewing tools I have. I use it for BBQ and all kinds of general cooking.

    Thermapen been the best brewing investment I’ve made. I calibrate all my thermometers with it. Also use it in the kitchen.

    I got the yellow one too.

    I bought a green Thermapen about three years ago. It stopped turning on when opened due to a bad connection. Sent it in for service and $25 later I had it back. It’s still turning off at certain spots when open. I think I might just buy a couple of their RT600C $19 thermometers as they work just the slightest bit slower.

    Yesh, I agree with Howie… $100 for a thermometer that only has a 1 year warranty???? Can it really be *that* much better than the $16 CDN thermometer? And what is “better” – Faster response time, more accuracy?

    With the CDN 5 year warranty, even if I had to replace mine every 5 years when the warranty runs out, it’d still be 25 years before I’d have spent the $100.

    One of the first thermometers I bought when I switched to all grain. Best purchase I made. Bought it on sale for $80, and it is faster than any of the other thermometers I’ve tried. Absolute must. It has also survived a couple of dunks with no I’ll effects.

    Just got my British Racing Green and so far so good. Bigger than I though which is a good thing. After some test runs with the Thermapen I grabbed my CDN and walked it over to the neighbors house and handed it to him since he was wanting one for when he is smoking food. Happy Birthday to me!
